@ Read whether there is people or object moving in the detection range of the sensor.
@ The sensor detection range and output delay time can be configured. Also you can restore the sensor to factory default settings.
@n Experimental phenomenon: When the sensor starts successfully, 0 or 1 will be printed on the serial monitor.
@ 0 means that there is no human or object moving in sensing area, 1 means the oppposite.
